Did you remember to update?

So ten (11?) days ago I wrote that long tutorial on setting up an rpi3 from pulling it out of the box to having MM² running. At that time I updated everything on the rpi, including the firmware. Booted up that same rpi today only to find another firmware available. This is just a friendly reminder to remember to update your rpi every so often, both the packages through 'sudo apt-get update ; sudo apt-get upgrade' as well as the firmware with 'sudo rpi-update'.
